Participants were scanned on a 3T Siemens scanner at the McGovern Institute for Brain Research at the Massachusetts Institute of Technology beteen 2006 and 2013. Functional data were acquired using echo-planar-imaging with voxel size of 3.125 x 3.125 mm and TE = 30ms, flip angle=90° , TR = 2 s. Slice thickness varied from 3.1 mm to 4.8 mm. Participants were scanned on either a 12- or 32-channel recive coil, both Siemens products. Data were analyzed using SPM8 and in-house software. The data were realigned to account for motion, smoothed with a 5 mm Gaussian smoothing kernel and normalized to a standard template in Montreal Neurological Institute space.
RFX was done on the false belief > false photograph contrast and thresholded at t >= 3 with a minimum cluster size of 10. The results were extremely robust resulting in:
- a contiguous cluster containing DMPFC, MMPFC, and VMPFC
- a contiguous cluster containing RSTS and RTPJ
- a contiguous cluster containg LSTS and LTPJ
To ameliorate this, the following boundaries were imposed:
- RTPJ and RSTS were separated by the axial plane at z = 4 (RSTS assigned all voxels where z < 4.)
- LTPJ and LSTS were separated by the axial plane at z = 7.
- DMPFC assigned all voxels z > 20.
- MMPFC assigned all voxels 20 >= z >= 0.
- VMPFC assigned all voxels z < 0.
With the exception of these boundaries, the entirety of the cluster was taken as the ROI. Both thresholded and t-map images (.img / .hdr) are available.
